The present invention relates to a novel accessory in the nature of anattachment for the neck 'of a mucilage or liquid glue bottle orcontainer, and the purpose of the device is to provide a reliable andconveniently usable glue dispensing applicatorwhich is in effect adispensing cap and spreader brush.

Under present prevailing circumstances, We find users of liquid glueattempting to apply it with precision to limited areas on Wood and otherconnectible parts and surfaces by various makeshift instruments. Someuse match stems, sticks of wood, and all sorts of haphazard instruments.Many resort to the use of the customary bristle brush which is generallysupplied with glue bottles and similar containers. I have discovered theneed for the adoption and use of a more satisfactory applying andspreading brush. Thus, as before indicated, it is my primary objectiveto provide an attachment which can be applied to conventional bottlesand which is expressly made, primarily of rubber, to function with arequisite degree of nicety in applying glue accurately.

In keeping with the expected requirements for an applicator possessed ofsimplicity and efficiency, I have found it expedient and practicable toadopt an attachment characterized by a pouch-like receiver, this beingdetachably connectible with the discharge neck of the glue can,

and having its discharge end fashioned to form a double lip controllablemouth through which the glue may be fed, according to prescribedconditions, and thereafter spread smoothly on the desired area of thework being acted on.

Furthermore, in accordance with the, dictates of my present judgment asto what constitutes an appropriate adaptation in this particular line ofendeavor, I have perfected the aforementioned pouch-type applicator, anoutstanding feature of 4,0 which is a properly reinforced dischargemouth forming the spreader, this having located therein hand controlledregulating means to restrict the size of the mouth and to thereby limitthe glue delivered for use.

Other features and advantages will become more readily apparent from thefollowing description and drawings.

In the drawings, wherein like numerals are employed to designate likeparts:

Figure 7 is a perspective view of the valving or regulator element.

Figures 8, 9 and 10 are perspective views of certain complementaldetails.

Figure 11 is an exaggerated detail section on the line ilii of Figure 2.

In Figure 1, a conventional mucilage or glue containing can orequivalent container is denoted by the numeral l2. this being providedwith the customary screw-threaded discharge neck it. The spreader cap orattachment is indicated, as a unit. by the numeral M. This is of generaldovetailed-shaped outline or configuration. Obviously, however, it maybe of any appropriate shape to properly dispense and spread the liquidglue in a desired ribbon-like stream. so that it may thereafter bespread along the desired surface (not shown). As before indicated, thebOdV portion of this attachment or device I4 is in the nature of areceiving hopper or pouch which contains a quantity of the glue when thecan is turned upside down, as shown in Figure 1. When the mouth of thepouch is completely open the glue runs freely therefrom onto the surfacebe 35 ing prepared for jointing. In fashioning this pouch-like receiverI have found it practical to utilize a pair of duplicate sheets ofrubber or equivalent members of the general configuration shown inFigure 8 and denoted by the numerals Hi. The numerals l6 designate slitswhich serve a purpose to be hereinafter described. The convergingmeeting edge portions of the two rubber sheets are molded, glued, orotherwise connected 5 together to define the pouch-like receiver. InFigure 6 the adhesive cement or other agent is indicated at H. Thetruncated or apex ends Hi are detached, and at this point a rubbercollar is is cemented or otherwise secured in place. 50 This forms asubstantially round mouth which snaps over the discharge neck l3 of thecan, as shown in Figure 1. The numerals 29 merely designate a metal stayor reinforcing strip to prevent over spreading of the pouch whereby tomain- 55 tain it against distortion and subsequent bursting.

Attention is next called to the discharge mouth denoted by the numeral2|. This is of longitudinally elongated form, and the stream of glue canobviously be allowed to gravitate therethrough onto the wood or othersurface being conditioned for jointing. This mouth is formed by placingrubber spacing blocks 22 and 23 between the opposed flaps or lips 24, asbrought out to advantage in Figures 3, 4, and 6. The blocks 22 and 23are cemented or glued or otherwise secured in place. They thereforemaintain the lips or spreading flaps 24 in parallelism. As shown inFigure 6, the numeral 25 designates a regulator which is in efiect avalving element. This comprises a band of rubber 26 anchored at one endon the spacing block 23. The opposite end is wrapped or wound around anadjusting bolt, that is, the shank portion of the bolt is indicated at2?. In accomplishing this, the free end of the rubber band is wrapped asat 28 around the shank 2'! and is provided with a reinforcing insert asat 29. Of course, the rubber could be thickened at this end andaccomplish the same result. The main idea is to render the free end ofthe band sufliciently rigid to permit it to be attached to theadjustable bolt 2'! in a reliable manner. The bolt has its threaded endprovided with a clamping nut 30. The numerals 3i designate washers.

The bolt 2i extends through the aforementioned slits I6 and then throughslots 32 provided in opposed duplicate metal cleats or strips 33. Thesemetal strips are bolted to the spacing blocks 24, as indicated by thefastening bolt 34. The main fastening means for-the strip, however,comprises a wire rivet 35 imbedded in the rubber, as indicated toadvantage in Figure '7. These riveted metal plates or cleats serve toproperly shape the discharge mouth 2|, that is, they hold the rubberflaps 24 substantially rigid and in parallelism. Moreover, the slots 32in said metal strips serve to accommodate the bolt 21 allowing it to beslid back and forth to stretch the rubber bandZfi and to fasten it in aset position. In Figure 3 we see the rubber band or valving element 25substantially in its open position. Thus, the left hand end of the mouth2! is partially closed. It is possible, however, to stretch this bandfrom left to right in Figure 3 and restrict the length of the mouth 2i,then tighten the nut 38 to maintain this adjusted discharge opening.

The gist of the invention is in the provision of the rubber doublewalled pouch l4 serving as an attachment and receiver for the dischargeneck of a glue can or equivalent container. The pouch has its dischargeend fashioned with spreading lips or flaps 24, these being associatedwith the discharge mouth 2! in which the valving means 25 is located toregulate the size of the mouth and to thereby regulate the dispensing ofglue. The metal strips 33 are important in that they serve asreinforcing elements in conjunction with the stay strip 28. They alsoserve to facilitate proper adjustable mounting of the valving element 25and, it will be noted'that the lips 24 extend beyond the so-called loweredges of these two metal strips so that the metal strips serve asbacking elements allowing the flaps to press thereagainst and to preventundue spreading and flexing of said applicator flaps or lips 24.

It is obvious that when the device is attached to the can and the can isturned upside down, the glue runs into the pouch and then dischargesthrough the delivery mouth 2|. It can then be conveniently spread by thebrushing or rubbing action of the flexible flaps or lips 24.

It is thought that the description taken in connection with the drawingswill enable a clear understanding of the invention to be had. Therefore,a more lengthy description is thought unnecessary.

While the preferred embodiment of the invention has been shown anddescribed, it is to be understood that minor changes coming within thefield of invention claimed may be resorted to if desired.
